A rotational spinning apparatus including an open container; a pivotally-leveraged drive with a manually-operable handle on its top and pivotable between down and extended positions and a rotating drive at its bottom and drivably connected to the handle; and a rotating member formed to sit rotatably within the container and drivably connect to the rotating drive. The rotating member defines an axis of rotation when in the container that runs centrally through the top and bottom of the container. When the pivotally-leveraged drive is placed over the container and the rotating drive is connected to the rotating member, the handle is pivotable along a plane substantially perpendicular to a plane perpendicular to the axis of rotation; and when so arranged and the handle is in the down position, both ends of the handle are intersected by a plane that is substantially perpendicular to the axis of rotation.

A pivotally-leveraged manual centrifugal drive according to a preferred embodiment of the invention for use with a bowl and a basket formed to nest within the bowl, comprising: a) a housing formed to mate with the bowl; b) a rotation wheel rotatably connected to the housing, formed to mate with the basket, and having a plane of rotation; c) a handle pivotally attached to the housing and oriented to move in a plane that is substantially perpendicular to the plane of rotation of the rotation wheel; and d) gears connecting the handle to the rotation wheel. Also disclosed are an automatic clutch that engages the rotation wheel only when the handle is moved in one direction, and a braking mechanism that includes a disk having a diameter substantially smaller than the rotation wheel.

A machine (1) for preparing a beverage comprises: a first part (20) and a second part (30) movable relative to the first part; a motor (51,51) having a drive member (510, 511) such as a rotating drive axis; one or more mechanical transmission members (52; 521-523; 524-526) for transmitting a movement of the drive member to the movable part (30) for moving the movable part; and a transmission frame (200) for supporting the motor and the movable transmission member(s). The transmission frame is an integral component (200) on which the motor and the transmission members are directly mounted.

An oil pumping unit with pinion reciprocating on rack has a base, a housing, crown block, a steel wire rope, a motor, a reducer, a pinion, and a rack. Rack seats are fixed on the inner sides of the front portion of the housing and the rack is secured on the rack seats. The two inner sides of the housing are guiding rails for the reciprocating frame. At each of the four corners of the reciprocating frame, a horizontal guiding wheel and a longitudinal guiding wheel are mounted, connecting to a pendulous frame via a hinge. The rear interior portion of the housing has a power cable box mounted, in the middle of which is an opening. Shelves are mounted on the upper portion of the housing. The steel wire rope (5) passes through the shelves.

The invention relates to a rack-and-pinion steering, including a toothed rack having a longitudinal axis, a toothed rack housing in which the toothed rack is guided for axial displacement between two end stops, and an end stop damping assembly which includes at least one stop ring and at least one elastic compression body, the compression body surrounding the toothed rack, and its spring/damping section having an axial length in a non-loaded condition. The stop ring has a continuously surrounding axial guide extension which is located radially inside in relation to the compression body and which has an axial length that is smaller than the axial length of the spring/damping section of the compression body.
